Sowing, propagation and operation methods of cornflower

Cornflower is a good material for cutting flowers, and it is often used in the layout of flower beds and borders, and flower friends can also plant plants at home. The cornflower, which symbolizes happiness, is a flower variety that many flower friends like very much. because the life span of the cornflower is not long, it is generally dominated by sowing and reproduction.

Cornflower

First, sowing and breeding:

Do not tolerate transplanting, should bring soil ball when planting. Basal fertilizer should be applied before planting. Proper watering during the growth period can prevent rotting roots, and topdressing liquid fertilizer once a month can promote growth. Its stem is slender, topping and coring at the seedling stage, promoting multi-branched lateral branches and plant dwarfing.

Main points of cultivation:

You can sow seeds in both spring and autumn, and autumn sowing is better. Sowing in the prepared seedbed in the middle and late September, covering the soil with no seeds, slightly compacting, covering with grass and watering enough water, often keeping the soil moist and going to cover the grass after germination. When the seedlings have 6 Mel 7 leaflets, they can be transplanted or planted with a distance of about 30 cm. After survival, 5 times water is applied to mature human feces and urine every 10 days or every month, and fertilization is stopped to wait for flowering in March of the following year. If potted, the potted soil should be loose and fertile, and the rotten leaves of garden soil, ash of plants and trees should be mixed with mixed soil. when the seedlings have six or seven leaves, they will be transplanted for the first time; when they grow later, they will be changed to three pots, because the cornflower has straight roots, and the big seedlings are not resistant to transplanting. It can be continuously buried in the soil in winter and taken out in early March. Fertilizing should be diligent and stop fertilizing when the bud appears. Suitable temperature for germination: 15 ℃ 20 min sowing time: spring-autumn. The suitable temperature for growth is 15 ℃ 25 min. Flowering period: spring-summer seedlings: choose loose and fertile soil as a bed, covering soil about 0.2 cm, about 8 Mel sprouting for 15 days. Cultivation: when the leaves of the seedlings reach 6 Mel 7, one plant will be planted in pots for every 13 mi 17 cm. After the seedlings survive after planting, pick the heart once, promote more branches, can blossom more, on the contrary, if there are too many branches, part of the lateral buds should be removed if necessary, larger flowers can be obtained. Because of taproot, it is appropriate to direct broadcast autumn sowing open field cover overwintering, early summer flowering, such as cold bed overwintering can blossom at the end of spring, spring sowing should be sown as soon as possible. It blossoms in June.

2. Sowing methods:

1. Raising seedlings: choose loose and fertile soil as bed, covering soil about 0.2 cm.

2. Cultivation: when the first leaf of the seedling is 6 Mel 7, one plant will be planted in pot every 13 mi 17 cm. After the seedlings survive after planting, pick the heart once, promote more branches, can blossom more, on the contrary, if there are too many branches, part of the lateral buds should be removed if necessary, larger flowers can be obtained. Because of taproot, it is appropriate to direct broadcast autumn sowing open field cover overwintering, early summer flowering, such as cold bed overwintering can blossom at the end of spring, spring sowing should be sown as soon as possible. It blossoms in June.

3. Use soil: prefer loose and fertile sandy loam with good drainage. The cultivated soil should be well drained and ventilated as far as possible. if the soil is sticky, it can be improved by mixing 40% snake sawdust or perlite.

4. Watering: watering once a day is enough in principle, but when it is drier in summer, it can be watered once in the morning and evening to keep the potted soil moist and reduce the temperature of potted plants, but avoid stagnant water.

5. Fertilization: the cornflower likes more fertilizer, and the three-element diluent should be applied once a month during the growth period. If the leaves are too luxuriant, the proportion of nitrogen fertilizer should be reduced, and more phosphorus and potassium fertilizer should be applied before flowering in order to get larger and beautiful flowers.

6. flowering management: cornflower can have natural lateral branches, and if there are more lateral branches, the flowers are smaller. If necessary, part of the lateral buds can be removed, and only smaller branches can be left, larger flowers can be obtained. Cornflower is a long-day plant, which has a short sunshine time in winter. If plant lamps are used to supplement lighting at night, it can be opened earlier.

How to plant corn chrysanthemum to propagate

Cornflower, also known as blue hibiscus, Cuilan, litchi chrysanthemum, etc., is an annual or biennial herb of the Compositae family, with high ornamental value, tall and straight planting plants, long pedicels, suitable for cut flowers, and can also be used as flower diameter materials. Dwarf plants are only 20 centimeters high and can be used for flower beds, grass edges or potted flowers. Let's take a look at the breeding methods of chrysanthemum.

Growth habits of cornflower

The hometown of cornflower is in Europe, it used to be a kind of wild flower, after many years of cultivation, the "wild" nature has become less, the flower has become bigger, and the color has become more. There are purple, blue, light red, white and other varieties, of which purple and blue are the most precious. There are everywhere in Germany's hillsides, fields, watersides, roadsides, front and back houses, and are regarded as the national flower in Germany. Its adaptability is strong, like sufficient sunshine, not resistant to wet shade, must be planted in a place with sufficient sunshine and good drainage, otherwise it will often lead to death due to dampness. More hardy, like cold and cool, avoid hot. Like sandy soil that is fertile, loose and well drained.

Propagation methods of cornflower

Cornflower seeds are generally sown in spring and autumn, of which autumn is the best, probably from mid-August to mid-late September. When planting, sow the seeds in the seedbed in the open field, gently compaction, and then pour the right amount of water, covered with grass, can germinate quickly, and remove the grass after sprouting. When the leaves grow to 6-7, they can be planted in November, and then 1:5 of rotten human feces and urine will be applied every 10 days or half a month until February to March of the following year. Potted sowing requires fertile and loose soil, and mixed soil such as rotten leaves is recommended.

Culture method of cornflower

1. Planting: after survival after planting, cornflower seedlings are plucked once to promote more branches and blossom more. On the contrary, if there are too many branches, part of the lateral buds should be removed if necessary, and larger flowers can be obtained. Because of taproot, it is appropriate to direct broadcast autumn sowing open field cover overwintering, early summer flowering, such as cold bed overwintering can blossom at the end of spring, spring sowing should be sown as soon as possible. It blossoms in June.

2. Potted soil: the potted soil of cornflower should be loose and fertile, and sandy soil with good looseness and drainage should be selected. it is best to use garden soil rotten leaves, plant ash and so on to be mixed with mixed soil. it is best to maintain good ventilation and facilitate drainage. If the soil is too sticky, 30% snake sawdust or perlite can be added into the soil.

3. Temperature: the cornflower has strong cold resistance and can be planted in open field in East China, while it must be covered in North China to survive the winter. Cut flowers are usually cultivated in greenhouse, sowed in August, planted in September, and can produce flowers in February of the following year. The warm land in the customs is usually sown from August to September, the open field is covered with overwintering, it is planted in early spring of the following year, and blossoms in early summer. The northeast is sown in spring in the greenhouse.

4. Watering: the cornflower is not resistant to shade and dampness, so it only needs to be watered once a day, but in the hot and dry summer, it is watered once in the morning and in the evening to meet the water demand and cool the soil at the same time. Pay attention not to pour too much water to cause accumulation in the basin.

5. Fertilization: the cornflower likes to be more fertile and needs fertile soil. During the growth period, the three-element diluent should be applied once a month. If the leaves are too luxuriant, the proportion of nitrogen fertilizer should be reduced, and more phosphorus and potassium fertilizer should be applied before flowering in order to get larger and beautiful flowers.

Matters needing attention of cornflower

1. The cornflower is strong, cold-resistant and sunny, requiring fertile, loose and well-drained soil.

2. Basal fertilizer should be applied before planting cornflower. Because the cornflower has a straight root system and is not resistant to transplantation, it is necessary to bring a larger soil mass when transplanting.

3. The stem of Chrysanthemum morifolium is thin and weak and is easy to lodge, so the planting distance should not be too dense. It is necessary to prevent the lodging caused by overdense growth and poor ventilation.

4. Cornflower needs to top and pick the heart at the seedling stage to promote more branches and dwarf the plant, so that it blossoms more and the plant shape is beautiful.

5. During the growing period of cornflower, liquid fertilizer should be applied once every 20 days, but it should be noted that more nitrogen fertilizer should be applied, and more phosphorus and potassium fertilizer should be applied properly to make the stem firm and the flower color bright.

6. the cornflower should be watered properly, not too much, and pay attention to timely drainage in the rainy season, otherwise it will cause rotten roots and affect the normal growth of the plant.

What is the flower language of cornflower? what is the planting method of cornflower?

Cornflower is a kind of ornamental herb, originated in Europe, with rich varieties, elegant plant type, large and gorgeous flowers, chic and beautiful flowers and various colors, among which purple and blue cornflower is the most valuable. Nowadays, cornflower has been widely planted, mainly in Europe, North America and other places. Next, the editor will briefly introduce the flower language of cornflower and the planting method of cornflower.

What is the flower language of cornflower?

The flower language of cornflower is meeting and happiness, while some people think that cornflower is meticulous, elegant, single happiness, yearning, love and loyalty, and so on. Legend has it that Queen Louis, the mother of the Prussian emperor William I, saw the blue cornflower on the way to escape, so she weaved it into a wreath and wore it on William's chest. William I later became emperor of Germany, so the cornflower is also regarded by the Germans as a symbol of the royal family and nation.

2. Planting method of cornflower

1. Raising seedlings

Seed propagation is the most commonly used propagation method of cornflower. First of all, we should prepare loose and fertile soil as a seedbed for seeds, and then sow seeds in mid-late September. When sowing, the seeds should be completely buried in the soil and slightly compacted, covered with grass and watered, always pay attention to the dry and wet condition of the soil, and replenish water in time to ensure that the soil is moist. When the cornflower sprouts, the cover of the seedling bed can be removed and taken care of patiently. When the seedling leaves of corn chrysanthemum grow to 6-7, they can be divided into pots and transplanted. after the seedlings survive, in order to promote more branches and more flowering, coring can be carried out once.

2. Cultivation place

Cornflower has strong adaptability, likes cold and cool environment, and is resistant to cold but avoid hot. Therefore, the cultivation place of cornflower should be cool and sunny environment.

3. Soil

Cornflower likes rich, loose and well-drained sandy soil, so weak clayey soil should be selected in cultivation, and fertile sandy soil is the best. If the soil viscosity is too heavy, you can add 3-40% snake sawdust or perlite to neutralize the soil viscosity, and pay attention to the soil drainage, keep the drainage smooth, and strictly prevent stagnant water.

4. Watering

Generally, you can water once a day. If it is a hot summer, you can water once in the morning and evening. When watering, you need to spray water on the leaves of the cornflower to keep the soil moist, but adhere to the principle of "dry and wet" and avoid stagnant water. During the rainy season, the soil should be often loosened and drained in time to prevent rotting roots.

5. Lighting

The cornflower likes the sunny environment and is not resistant to shade and dampness. it is necessary to ensure the duration of sunshine in cultivation, and plant lamps should be used to supplement light at night in winter when the sunshine is relatively short, so that the cornflower can get enough light for a long time to promote its early flowering.

6. Fertilizer

Cornflower likes to be more fertile, and appropriate fertilizer should be applied during cultivation in order to ensure good growth. The main fertilizer is nitrogen fertilizer. In order to make the flowers large and beautiful before flowering, the application of nitrogen fertilizer should be reduced and the proportion of phosphorus and potassium fertilizer should be increased. If the branches and leaves of corn chrysanthemum are too dense, the application of nitrogen fertilizer can be reduced appropriately. In addition, the three-element diluent should be used once a month.

7. Pruning

In order to ensure the size and color of the flowers, the side branches of the cornflower should be trimmed and some of the lateral buds can be removed if necessary to retain small branches.

The flower language of cornflower is meeting and happiness, and its breeding is also very simple. As long as we pay attention to temperature, light, watering, fertilization, branch and leaf pruning and other factors, cornflower will grow very well. Friends who like cornflower can try to plant a pot.
